2015 yamaha r1 ecu flash full#

It can’t be done on the dyno since the front wheel is immobile.

So I had to take the bike off the dyno to test this one. I did about 20 changes and found a rpm that the bike really liked and saw a nice jump in power strictly from this change Variable stacks are probably Yamaha’s greatest feature. This test involved adjusted at which point the stacks raise and lower.

I’ve adjusted this to shift as fast as possible at full throttle and to smooth out part throttle as well (you can see this in my videos) Oem kill times are pretty slow and the bike would dip hard on shifts and lose momentum. The kill times for the QS were adjusted per rpm range and per gear. Part throttle and full throttle have Been adjusted.Įngine brake was nicely smoothed out snd made more linear instead of progressive. Midrange timing had minimal adjustments.įuel was adjusted in all areas and a lot was needed down low as the initial hit was very lean. Timing at WOT was adjusted to safely increase power with detonation. Timing down low was altered to help the bike run cooler. Ignition timing has changed drastically also. The on/off/on throttle transitions are smooth as butter. All modes have full power at WOT, but the rate at which it reaches full throttle is different at each PWR mode.

PWR 1 is the most aggressive and tapers down to PWR 4. Available for: 2020-2024 Yamaha R1 and R1MĮach PWR mode has fully optimized throttle mapping.
